being for the mind, even as motion--while the immediate purpose of the
locomotive--is not its chief end. The steam engine may stand in the same
spot while its wheels revolve madly; it may move along the tracks alone,
and accomplish nothing; or it may transport a great train of loaded
cars. Unless it moves to some definite point and carries merchandise or
people there, it is a useless, indeed, a dangerous invention. We find,
in fact, that it functions to the very definite end of taking man and
his chattels to specified places.

And so it is with the mind. If it is thinking and feeling and willing
only for the sake of exercising these mental powers, it might better not
be. But what end do we actually find these functions serving?

Mind, with its powers of thinking, feeling, and willing, gives an
external world of matter; an internal world of thought, and so relates
them to each other as to make them serve man's purposes. Thus these
functions exist for accomplishment.

In the solving of a problem, for instance, the mind thinks, primarily;
in the enjoyment of music it feels, primarily, though its feeling may be
determined by the intellectual verdict on the music; in forcing its
owner to sit at the piano and practice in the face of strong desire to
attend the theater, it wills, primarily. Now one of its functions
predominates; now another. But the whole mind, not a feeling section, or
a thinking section, or a willing section, operates together to produce
action. When I play the piano it calls on all my mind. I think the
music. I feel it. I make my fingers play it. But the thinking, the
feeling, and the willing act together to result in the fingers playing.

The mind, then, is an instrument of achievement. It fulfils its purpose
when it makes matter serve useful ends.

_Emotion_ or _feeling_ is the function of the mind which associates a
sense of pleasure or pain with every thought or act.

Feeling is the affective state of mind. By this we mean that it has the
power to move us. And this emotion primarily does; for our feeling of
pleasure or pain moves us to action, as well as precedes and accompanies
and follows action. The word _emotion_ is usually employed to denote an
acute feeling state, while the word _mood_ denotes a prolonged feeling
condition, _i. e._, a less acute emotional state. The word _feeling_,
however, is used to cover both; for in each case the sensational element
manifests itself in a definite ph
